Re: Pulled the trigger today ...
I emailed Richard Iskenderian about the benefits and longevity of the Helix optioned lifters and here is his reply;
Thanks for being a loyal Isky Customer !
The Helix Bushing is designed for Supercharged, Turbocharged and/or High Spring Load Normally Aspirated Applications & Street Applications with a good amount of idling, to allow you to get extra oil to the bushing.
We have discontinued the EZX Bushing and only use the EZMAX and EZHELIX options now.
Unless your loads are extreme on the street ( over 900 lbs open ) , normally the EZMAX works just fine. There is nothing negative about using Helix on the street , especially if you want additional insurance. It may not be
totally necessary .
You should see some extra life on the street but it will depend on your open spring loads. I wouldn't say you
could double the life but expect somewhere between 25-50% more life on the street with the Helix.
Hope this information helps.
So they are probably overkill for my application as my open spring load is under 700 lbs.
But,for me,the added insurance is just peace of mind for me.
The extra cost is pretty small when looking at the big picture.
If I can get up to 50 % more life from these lifters it is well worth it to me.
And at a later date I can send my current lifters for an upgrade to the Helix option.
Two sets should last me a very long time
